Mediaval builders utilized a diverse range of stones, including:

• Imported Stone: The yellowish-white oolitic stone of Caen was significant, known for its softness when quarried and its ability to harden upon exposure, making it ideal for delicate carvings.
• Oolitic Limestones: Various kinds of oolites were widely used, particularly from quarries in Barnack, Doulting, and Portland.
• Magnesian Limestone: Found in places like Huddleston, this stone was durable and easy to work with.
• Cretaceous Stones: This group includes chalk, with harder forms known as clunch, frequently used in East Anglia.
• Carboniferous Stones: Gritstones from Derbyshire and Lancashire were durable but difficult to carve.
• Stones for Internal Decoration: Purbeck marble was commonly used for internal decoration and sculpture.

These stones were sourced from various quarries across England, reflecting the regional availability and the specific requirements of the construction projects.
